Laundry Effluent Treatment
CeraMem® Ceramic Membrane Systems
WATER TECHNOLOGIES
Unique Laundry Effluent
Treatment System
Using CeraMem® Ceramic Membranes
Water is one of the most critical components in industrial laundries. Costs
are associated with the large volumes used and subsequent disposal of
detergent-laden wastewater.
Veolia Water Technologies, with a long history of successful installations
in industrial laundries, has developed a system that offers substantial
savings in water, power consumption, detergent, and sewer costs. Based
on CeraMem® ultrafiltration (UF) ceramic membranes, these systems
provide an effective technology platform for laundry applications.
Modular, Automated, and
Fully Integrated
American Technology,
Engineering & Equipment
The system is supplied as a compact, modular unit with flexible features
and capacities that can be fully integrated into each unique laundry.
System Features:
• Pre-engineered, skidded system
• Flexible, scalable capacity from 50-250 gpm
• Utilizes full-size CeraMem® UF membranes
All tanks, pumps, instrumentation, controls and other ancillary equipment
are supplied by Veolia. As a total solution, each system is adapted to each
laundry’s needs and based on a pre-engineered, modular design.
High Recovery Rates:
• 50-70% as stand-alone unit
• >90% with RO system to remove chlorides

System Benefits
•Water and heat recovery:
•Water reuse reduces
makeup water costs
•Decreased energy
consumption
•Increased water quality for
reuse, even on critical white
laundry applications:
•<5 mg/l suspended solids
•<5 mg/l dispersed oils &
greases ensures quality of
laundered product
•Reduction in regulated
contaminants to minimize
POTW surcharges and
penalties

Laundry Market Experience
CeraMem® Technology was the first commercially available, monolithic, ceramic
membrane solution in the water treatment industry.
Veolia introduced its first industrial laundry effluent treatment system in 1991.
Its performance met and exceeded regulatory limits.

Why Veolia?
Veolia is the largest water
technologies and service
company in the world.
With over 150 years of
experience and more than
350 proprietary technologies,
Veolia provides the expertise
required for applications
focused on optimization of
water reuse.
• First Veolia system for “light laundry” application in 1991, USA
• Slightly heavier than typical white laundry
CeraMem® Technology
Veolia’s ceramic membrane technology is ideal for industrial applications
with high operating temperatures (>40°C), chemically aggressive process
streams (high/low pH), and removal of emulsified oil & grease.
Features & Benefits:
•Chemically durable, highly abrasion resistant membranes
•Excellent flux rates
•High packing density with 10.5 m² of membrane area per element;
available in 2 mm and 5 mm channel sizes
•Reduced power consumption through reduced crossflow velocity
without adverse fouling
•Life-cycle costs less than polymeric membranes
